Did anyone else have similar symptoms?

Around mid November i had extreme bloating. It was really bad and came on randomly. I have had this once before back in May, accompanied by lower abdominal pains due to being constipated. One visit to the doctor, and he prescribed me something that helps with constipation/bloating/constipation pain, and within 5 days all bloating and pain was gone, and i never once experienced this again until November. In December i found out i was pregnant, and went to the ER due to some really bad lower abdominal/pelvic pain, and really bad back pain. During this visit, they took a urine sample, which came back with +2 blood in the urine. The doctor at the time said i had blood in my urine because i was pregnant. About a week after the ER visit, i went to the ER again due to cramping and bleeding, and i had a miscarriage. My urine test results from the ER came back testing negative for everything they test for, i.e. protein in urine and all that stuff, so that rules out all infections, and i thought maybe my symptoms were due to pregnancy, but i am not pregnant anymore, and the symptoms still remain.The bloating/constipation actually seemed to subside during my pregnancy, but since i miscarried it has come back. A transvaginal ultra sound during my ER visit did show that i had a cyst, but they said that it was very small, and they did not see it as any cause of concern as they are very common during pregnancy, and usually disappear on their own. I went back to a doctor a few days ago, as the blood in the urine has been in the back of my mind, and the other symptoms are still present. I assumed that if blood in the urine was due to early miscarriage bleeding, it would be gone by now seems it has been over a week or so, and sure enough, i still have blood in my urine and tested negative for all the stuff that shows some sort of infection. I went to one of those urgent care places which i feel was a complete waste of time seems he prescribed me meds for a UTI, and my urinalysis was negative for nitrites, but i feel they felt they have to give me something. A few days ago i had my well woman exam, so i told my OB about the urinary symptoms and she has ordered a urine test and urine culture. I feel a complete idiot, but i never thought to mention the constipation/bloating/back pain to my OBGYN, as i was thinking of going to a gastroenologist to see if i was having some digestion issues, but then yesterday i started looking further into my symptoms, and i have every symptom of ovarian cancer. I am in no way saying i have cancer, but i do have symptoms that are very worrisome to me. The problem is, due to my age, pregnancy, and then sadly after miscarriage, i feel that all doctors i see are relating my symptoms to those things, and i really do feel that it could be a problem they are overlooking. I am not sure if i should wait for my OBGYN to get back to me with the urine results, and for me to bring up my other symtpoms, or whether i should go to a GP. My back pain is really bad today, and i feel sharp pains every now and then in my pelvic area, mostly on the left side, and sometimes on the right. I have increased gas, my urination issue are still present, a little bloating, tiredness, feeling full very quickley, and nauseous. I am so scared, and i want to find out what the issue is fast, and my OBGYN said it make take a few days to get the urine culture testing back, but i really don't want to wait any longer. My back pain is just so bad. I was wondering if anyone else had these symptoms? I have not found anything on the internet that says blood in urine is a sign of ovarian cancer, and the blood is not visible, it is a very small amount only seen under a microscope, but all the other symptoms worry me a lot, and i was wondering if anyone else experienced something similar?
